I bought this drill based on a tool shootout of high amperage 1/2 inch drills in tools of the trade magazine. This drill came out head and shoulders above the offerings from hitatchi, makita, dewalt, portercable and bosch. The highlights of this drill are gobs of torque(It will twist your arm if you are not careful!) solid yet lightweight construction, a long, heavy gauge ruber 3 prong cord, a heavy duty keyed chuck. I picked this drill up at the home depot during a tool trade in promotion(traded in an old single speed metal bodied black and decker 3/8th drill.) I have been so impressed at the capabilities of this drill. It has driven 4 inch long 3/8ths lag screws without a problem. It will stir a paddle bit in drywall mud and drive up to a 2 and 9/16ths self feed bit. This is one incredible tool. I will be replacing the keyed chuck with a keyless though.
